摘要
根据智能网关在液压支架智能分布式网络数据采集系统中的功能需求,提出了一种基于Cortex M3的实时网关设计方案,介绍了网关的硬件和软件设计。该网关实现了RS485或CAN总线井下压力数据的批量采集,可以通过以太网或Modem远程上传数据到上位机,使用SD卡实现大量采集数据的离线备份。试验结果表明,该网关具有成本低廉、结构简单、稳定可靠的优点。
According to functional requirements of intelligent gateway in smart distributed network data acquisition system of hydraulic support,a design scheme of real-time gateway based on Cortex M3 was proposed,and designs of hardware and software of the gateway were introduced.The gateway realizes batch sampling of pressure data through RS485 or CAN bus,can upload data to the remote upper computer through Ethernet or Modem,and can offline backup massive sampled data using a SD card.The experiment result shows that the gateway has advantages of low cost,simple structure and high stability and reliability.
